What is GEO (Generative Engine Optimization)?

GEO stands for Generative Engine Optimization. It is the practice of optimizing your website to appear in AI-generated answers from ChatGPT, Perplexity, Google AI Overviews, and Claude. Foglift is the first tool to combine SEO and GEO analysis in one scan.

What does Foglift analyze?

Foglift scans websites across 5 categories: SEO (meta tags, headings, Open Graph), GEO (AI-crawler access, structured data, citation-readiness), Performance (Core Web Vitals, load time), Security (HTTP headers), and Accessibility (WCAG compliance, contrast, alt text).

How is Foglift different from Ahrefs or Semrush?

Ahrefs and Semrush focus only on traditional SEO. Foglift is the first tool to combine SEO + GEO (AI search optimization) analysis, checking if your site is ready for AI-generated answers. It starts free and costs 10x less than alternatives.

Does Foglift have an API?

Yes. Foglift offers a free public REST API at foglift.io/api/v1/scan that returns JSON results. Developers can use it from the terminal, CI/CD pipelines, or AI coding assistants like Claude Code and Cursor.

Detailed Comparison

Pricing

Sitechecker starts at $49/month for its Basic plan, scaling up to $249/month for premium tiers. You get a 7-day free trial, but you need a credit card to start. After the trial, you're locked into a monthly subscription. Foglift offers unlimited free scans — no credit card, no signup, no time limit. The Deep Scan ($9 one-time) provides a comprehensive report with AI recommendations. Pro is $49/month for unlimited scans and monitoring. That's a $9 one-time payment vs $588/year with Sitechecker.

GEO Analysis — The Key Differentiator

Sitechecker focuses on traditional SEO — crawling, rank tracking, and backlinks. It doesn't analyze whether your site is optimized for AI search engines like ChatGPT, Perplexity, or Google AI Overviews. Foglift includes a full GEO (Generative Engine Optimization) score that checks AI crawler access, structured data depth, FAQ detection, entity markup, and citation-friendly formatting. As AI search rapidly grows, this is becoming essential for maintaining visibility.

Standalone Tools

Foglift offers 26 free standalone tools (SSL checker, DNS lookup, WHOIS, accessibility checker, contrast checker, page speed, robots.txt tester, website carbon calculator, and more) that work independently without creating an account. Sitechecker bundles everything into a single platform that requires signup and a subscription. If you need quick checks on specific aspects of a website, Foglift's individual tools are faster and free.

Where Sitechecker Wins

Sitechecker includes rank tracking and backlink monitoring that Foglift doesn't offer. If you need to track keyword positions over time or monitor your backlink profile, Sitechecker bundles these into one platform. It also provides scheduled site crawls with change detection. However, for rank tracking and backlinks specifically, dedicated tools like Ahrefs or Semrush provide significantly deeper data at similar price points.

✓Want free, unlimited website audits without signing up
✓Need GEO / AI search optimization insights
✓Use individual tools (SSL, DNS, accessibility, carbon, etc.)
✓Want API access or MCP integration for AI assistants
✓Prefer a one-time $9 payment over $49/month subscriptions
